    Looking for a function...

    Is there a function like this:
    nofv(int i, char c)
    That returns a string of i c's? Such as this:
    nofv(5, "m")
    Would return a string of "mmmmm"? Or will I have to make my own? Thanks !

    Since this is the C++ board, I'm assuming that STL solutions are acceptable. If that's the case, then a std::string constructor will do exactly what you want:
    Code:
      std::string str(5, 'm');
      std::cout << str << std::endl;
      /* output: mmmmm */

    Well, I'm not too excited to use strings (I like them, just char arrays would work better in my case). Thanks anyway !

    Code:
    #include <iomanip.h>
    
    int main() {
    	cout << setw(6) << setfill('m') << endl;
    	return 0;
    }

    You would have to pass the array you want to store it in, otherwise you return a pointer to a temporary object...It would be easy to write a function like that, but I think you could just use the memset function
